You are correct about what type of accent is to be used in this case, however I feel compelled to attract your attention to the fact that you spelled "aigue" incorrectly.
It should be "aigu", not "aigue", because the adjective derives its gender form from the noun's (here "accent"), and "accent" in French is masculine so "aigu" must be as well, and the final "e" would only be appropriate if the noun were of the feminine gender.
This thread is going weird places, isn't it
